alexdok [17]

so from 1992 have been: 2016 - 1992 = 24 years

November + December + January + February = 4 months
and some days more, 19 days because today is 19th, so the total is:

 (6 pts) The average age of CEOs is 56 years. Assume the variable is normally distributed. If the SD is four years, find the pr
Alenkinab [10]

Answer:

The probability that the age of a randomly selected CEO will be between 50 and 55 years old is 0.334.

Step-by-step explanation:

We have a normal distribution with mean=56 years and s.d.=4 years.

We have to calculate the probability that a randomly selected CEO have an age between 50 and 55.

We have to calculate the z-value for 50 and 55.

For x=50:

z=\frac{x-\mu}{\sigma}=\frac{50-56}{4}=\frac{-6}{4}=   -1.5

For x=55:

z=\frac{x-\mu}{\sigma}=\frac{55-56}{4}=\frac{-1}{4}=-0.25

The probability of being between 50 and 55 years is equal to the difference between the probability of being under 55 years and the probability of being under 50 years:

P(50
